Read the installation instructions for your stereo. If you no longer have it, you may be able to download it from the manufacturer's site.
Preamp is defined as before amplifier. These outputs connect to an amp through a patch cable. If your stereo has outputs that connect directly to your speakers those are amplified signals(to varying degrees).
I'm not familiar with the amp you are using. If you are using it for your sub only, then you can technically use either of the preamp outputs. You may see if you can switch one to a non-fading output if you are planning to run it with only the sub. Depending on the stereo this may allow you to control the volume of the sub from the deck seperately or even turn off the sub, say...if your mom will be riding with you or something. It will also keep the fader from affecting the signal strength.
If you can not change it to a non-fading output, then you need to decide you're preference as to which set of preamp outputs you will use. When I ran a basic set-up back in the "I'm too poor high school days" I ran my subs off the rear preamp output so that if I wanted to turn down the sub I would just fade the music to the front speakers. I'd lose the rear speaker sound, but it was usually temporary anyways.
If the amp is a multi-channel unit and you plan to run more than just a sub, describe the rest of your set-up and the amp. This could easily become a long post, but I don't feel like typing out endless possibilities. I'd rather narrow it down to the options you have. I already typed up the stuff above before I thought about this so that will just stay up.
